In different parts of India, the currency is known as the rupee, roopayi, rupaye, rubai or one of the other terms derived from the Sanskrit rupyakam. The most commonly used symbols for the rupee are ₹, Rs and Rp.

The rupiah (Rp) is the official currency of Indonesia and is subdivided into 100 sen. The name derives from the Indian monetary unit rupee which is called as rupiya in Indian languages. Informally, Indonesians also use the word "perak" in referring to rupiah. Inflation has now rendered all coins and banknotes denominated in sen obsolete.
